Many FOSS projects are all about the fun of programming them, not about having a user base. Such projects get put "out there" in the hopes that someone might someday find them useful, but it doesn't really matter to the people working on them whether they ever have a substantial user base, as long as it continues to be fun to program and work on the project.
If user base was what counted to me, I'd have abandoned MSS Code Factory years ago. To this day I've never had more than 100 or so downloads in a week, and usually more like 10-20. But it's fun. It keeps me entertained. And that is what really "matters" to me; not it's popularity.
"Popularity breeds contempt."
